Introduction
Every XP or P9000 disk array that is connected to an instance of HP XP P9000 Performance Advisor
must have a valid HP XP P9000 Performance Advisor license to monitor the internal raw disk
capacity of the XP disk array or the usable capacity of the P9500 disk array. HP XP P9000
Performance Advisor monitors the internal raw disk capacity in an XP disk array or the usable
capacity in a P9500 disk array for which a license is generated at the Hewlett-Packard Authorization
Center (HPAC) website (URL: http://webkey.external.hp.com). To monitor internal raw disk
capacities, generate Permanent licenses. To monitor usable capacities, you can generate Permanent
and Meter based Term licenses. For more information, see “HP XP P9000 Performance Advisor
licenses” (page 21).
The internal raw disk capacity refers to the total capacity of all the RAID groups created on the XP
disk array. It excludes the disk capacity occupied by the external RAID groups and pool volumes,
such as the thin provisioning pools and the virtual volumes.
NOTE: If there are unprocessed RAID groups (those without LDEVs) and you see a difference
between the actual internal raw disk capacity and the value displayed in HP XP P9000 Performance
Advisor, HP recommends that you use outband mode of configuration data collection to get the
accurate data.
The usable capacity is calculated as the sum of the following: Total allocated LDEV capacity + total
unallocated LDEV capacity + reserved capacity.
• Total allocated LDEV capacity includes the allocated internal LDEVs
• Total unallocated LDEV capacity includes the unallocated internal LDEVs
• Reserved capacity includes the pool volumes, such as thin provisioning, snapshot, and
continuous access journal volumes
So, usable capacity = Internal LDEVs  (External Volumes + Virtual Volumes)
